沉淀池水流动特性分析与应用

On Water-Flow Character Analysis and Application of Sedimentation Tank

采用雷诺平均N-S方程以及标准k-ε湍流模型,在以压强连接的隐式修正法(SIMPLE-C)算法建立的压力速度校正方程基础上,对水厂污泥池的三维水流动进行了求解。数值模拟结果与污泥池使用过程出现的问题较符合,结合计算结果对入水口布局进行了合理的设计,所得结论对水厂沉淀池的结构改造及优化设计具有一定的指导意义。

Using Reynolds＇ Averaged N- S Equation and the standard k-ε turbulence model and based on the emendation equation of pressure speed conducted by SIMPLE - C calculation of pressure intensity connection, the paper computes three - dimensional water flow in the sedimentation tank of the water works. The result of numerical simulation accords with problems arising in use of the tank. As a result, the layout of the water inlet has reasonably been designed. The conclusion will be of guiding significance to change of structure and optimization design of the tank.
